Exhaust temperatures/heat shield
MOrning All,
I've just been thinking about the sort of temperatures that exhaust pipes get upto in operation. And I don't really have a clue, other
than hot!
Basically, I'm a bit worried about having things like wiring and hydraulic pipes passing too near the exhaust pipes, if it is going to get
stupidly hot.
Also, what is the general opinion on exhaust wrap (the fibreglass type stuff with a shiny aluminium foil on one side) Are there any reasons why I
shouldn't wrap an exhaust in it to reduce the under bonnet temperatures?
Cheers
Andy

I've seen heatshields fitted to protect brakepipes.
Isn't the real answer to route things so they don't go near the exhaust?

Yeah, I would agree with you on that point. As my car is mid engined (its a Sylva Mojo, and not stricly a locost  ) the exhaust has to pass very
close to the rear bulkhead which also forms the back of the drivers seat. Obviously I want to keep the temperature down as much as possible in this
area, hence my query about exhaust wrap.
I knowthere was a Heatshield fitted to the clutch hydraulic line on the Mk1 mr2, where it passed near the exhaust, so I think I'll have to
replicate this somehow..

I had to tiewrap my clutch cable back after the first one melted. It's about 4" from the downpipe now and it seems alright.

I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
